Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the vehicle’s 12V battery for safety.

2. Adjust Toe Angles

Tools Required: Alignment machine or toe gauge, wrenches.
Identify the current toe angle readings.
Loosen the tie rod end lock nuts.
Adjust the tie rods to achieve the desired toe angle (typically 0.05° to 0.15°).
Retighten the lock nuts to the manufacturer’s specified torque (consult service manual for specifics).

3. Adjust Camber Angles

Tools Required: Camber gauge, wrenches.
Measure the current camber angle on each wheel.
If adjustments are necessary, loosen the bolts securing the strut to the hub assembly.
Adjust the camber by moving the strut either inwards or outwards.
Retighten the bolts to the manufacturer’s specified torque.

4. Adjust Caster Angles (if applicable)

Tools Required: Caster gauge, wrenches.
Measure the caster angles using the gauge.
Adjust the caster by moving the upper control arm.
Ensure it is symmetrical on both sides to avoid pulling.

5. Final Alignment Check

Tools Required: Alignment machine.
Once adjustments are made, recheck all alignment angles.
Ensure all measurements are within the manufacturer’s specifications.
Test drive the vehicle to confirm the alignment is correct.
